Timeline of behavioral testing and predatory stress. Behavioral testing was conducted prior and following chronic stress in order to measure the effects of the stress paradigm on anxiety- and depressive-like behaviors, as well as on cognition. Behaviors were completed in the following order before and after stress: sucrose preference, open field, novel object, marble burying, and social interaction. Predatory stress lasted 15 days and post-behavioral testing began the day after the end of stress.
